display type abbreviations such as OLED, LCD, QLED, and more. When comparing panel types from different categories, like LCD versus OLED, the distinct characteristics are simpler to observe, but when examining similar technologies, it becomes more challenging to differentiate. We’ve previously explored OLED versus QLED TVs, so let’s now compare QD-OLED with OLED.
On OLED (Organic Light-Emitting Diode) televisions, each pixel in the panel emits its own light independently, and when a pixel is not in use, instead of showing a dark color, it just stays off. This feature allows OLED panels to exhibit what is known as true or more authentic blacks. Dark scenes and images do not look washed out as there are no backlights involved. This significantly influences contrast ratio, color precision, especially in darker hues, brightness, viewing angles, and the refresh rate of the panel. OLED utilizes a white layer to generate light, which then passes through filters to create colors like red, green, blue, and white.
QD-OLED (Quantum Dot Organic Light-Emitting Diode) panels incorporate a blue-emitting layer, as opposed to the white layer found in OLEDs. This layer “excites” Quantum Dots by shining light on them, producing the necessary colors to form the image on the screen. With the foundational layer being blue, it yields more vibrant colors, enabling the panels to achieve enhanced color saturation, greater brightness, and extended lifespans. QD-OLED displays also integrate well with various technologies like HDR or Dolby Vision.
